Humans are emotional beings and tend to show their emotions intensely through facial expressions, which has a significant visual impact on facial features [1]}.
Therefore, modern face recognition algorithms must be able to handle a wide range of facial expressions.
The Multi-PIE [2]} dataset with its protocol E is used to test the algorithms against a variety of expressions seen in Fig. fig:multipie-expression-img.
64 identities are used in the dev set, and the eval set is composed of 65 identities.
Five faces per identity with neutral expressions were considered for gallery template enrollment.
